What are Softsubs and How to Add or Remove Soft Subtitles Efficiently

Soft subtitles, also known as softsubs or closed subtitles, are text tracks that can be turned on and off during video playback. Unlike hard subtitles, which are permanently burned into the video frames, softsubs exist as separate files within the video format.

However, it is important to note that not all video formats support soft subtitles. Common video formats used to store soft subs are MKV, MP4, and MOV. Other formats, such as AVI, WMV, and MPG, do not accept soft subtitles.

To view or hide soft subtitles, you'll need a media player with subtitle support, like VLC, Windows Media Player, MX Player, or KMPlayer.

Soft subtitles are particularly helpful for watching foreign films or learning new languages, though they can sometimes be a distraction. If you need to add soft subtitles to MP4/MKV/MOV or remove soft subtitles, the following sections will guide you through the process easily and quickly.

To add softsubs to your videos, you'll need a reliable program. We recommend WonderFox HD Video Converter Factory Pro. This powerful yet easy-to-use tool is designed primarily for video conversion but also excels at handling subtitles. It enables you to soft code subtitles to MP4, MKV, or MOV files without re-encoding, hence keeping the original video and audio quality.

Now, I will demonstrate how to add soft subtitles to MP4 using this software. Before start, please free download the software and install it on your PC.

Launch HD Video Converter Factory Pro and open Converter. Click + Add Files to load your video into the program or drag and drop the file directly.

In the main workspace, click the "+" button next to the "T" option to add your subtitle file. You can add multiple subtitle tracks if needed. Next, select the H option and change the subtitle type to CC (Closed Captions). Repeat this step for each video if you're processing multiple files.

Note: If you have added multiple subtitles, ensure all the desired tracks are selected under the "T" option after switching to the CC type.

Click the ▼ button at the bottom to specify an output path or leave it as default. Finally, hit Run to start the process. The software will handle the rest, and your subtitles will be added in no time.
